Current situation
The overlay mount shortly disappears during
systemd-sysext refresh. When the overlay fails to assemble, nothing is mounted.Impact
Services may be down for some time and there might be race conditions. A misconfiguration brings all overlays down.
Ideal future situation
Make
systemd-sysext refreshreplace the overlay mount atomically with Linux 6.5 "mount beneath", and then unmounting the old one with a regular lazy umount (but leave it when no new mount could be assembled).Implementation options
